Abstract: A method includes forming a single-crystal-like metal layer on a metal seed layer, the metal seed layer formed on a sacrificial wafer. An anchor layer is formed on the single-crystal-like metal layer. The single-crystal-like metal layer is separated from the sacrificial wafer via the anchor layer. The single-crystal-like metal layer is transported via the anchor layer to a target substrate having one or more recording head subassemblies. The single-crystal-like metal layer is joined with the recording head, the single-crystal-like metal layer being integrated with the recording head as a near-field transducer.

Abstract: A method of manufacturing an electronic device includes a positioning step of positioning a first member supporting a laser diode with respect to a second member having a waveguide, a bonding step of bonding the first member and the second member together, and a checking step of checking the accuracy of positioning of the first member with respect to the second member. In the positioning step, the laser diode is energized to allow laser light to be emitted, and the laser light is allowed to be incident on the incidence end of the waveguide. In the bonding step, a bonding material is melted by irradiating the first member with heating light while the laser diode is not energized. In the checking step, the laser diode is energized again.

Abstract: Alignment of a near field transducer (NFT) optical input coupler and a light emitting device involves providing excitation radiation from an excitation light source through an optical input coupler to the NFT and filtering output radiation from the NFT using a short wavelength pass optical filter. The optical input coupler is scanned through multiple positions while the photoluminescent radiation is detected. A first alignment position between the NFT input coupler and the excitation light source is identified based on the detected photoluminescent radiation. A light emitting device is scanned through multiple positions the light output is detected by a detector. A second alignment position between the light emitting device and the detector is identified. The first and second alignment positions are used to align the light emitting device with the optical input coupler.

Abstract: An apparatus comprises a slider of a magnetic recording head, a submount, and an interface defined between the slider and the submount. A laser diode is connected to the submount. A metal layer is provided at the interface between the slider and the submount. The metal layer connects at least about 30% of the surface area of the submount at the interface to the slider and serves as a thermal conduction pathway between the submount and the slider.

Abstract: An air-bearing surface of a slider is coated with a photoresist having a high optical absorbance at or near an operational wavelength of the slider. Light is directed at a target wavelength through an entry of a waveguide integrated into the slider. The light exiting the waveguide forms a feature through the photoresist, the feature proximate a near-field transducer of the slider. A sub-micron pattern is formed using the feature.
